  • Solidification of high quality alloy semiconductors
    Patent number: 9109299
    Abstract: An alloy semiconductor can be grown using a container including a lower section containing a composition-control source material and an upper section containing a solid. The composition-control source material is heated to produce a vapor, and the solid charge is melted to form a melt with a melt meniscus extending to an inner surface of the container. The vaporized composition-control source material flows from the lower section to the upper and contacts the melt meniscus. The melt is then cooled to form a crystal.
